We figure it will be a while before the industry fixes all our battery woes, so you best prepare yourself with a handy portable battery pack for now. These nifty accessories can charge your devices on-the-go, effectively elongating your battery life by substantial proportions. Today’s deal highly discounts a 10,000 mAh battery from KMASHI, taking its price down to a mere $13.99.

Let’s put this into perspective: a Samsung Galaxy S6 comes with a 2550 mAh battery, while an LG G4 packs a 3000 mAh one. This means you should be able to get over three times the capacity from this external battery, when compared to your average mobile device’s juice.

And the discount is nothing to scoff at, either. This portable battery pack’s original price is $49.99, meaning those who take advantage of this deal are getting a 72% discount. Not to mention, it’s hard for battery packs of this size to come by at such low prices, regardless of the MSRP. Add in the fact that you get free Amazon Prime shipping, or free standard shipping in orders above $35, and we have a winner.

The KMASHI 10,000 mAh battery pack can charge two devices at once, through a couple USB ports. One of these can output at 5V/2.1A. The second one is a bit slower at 5V/1A, but it will still do. These slower ports are usually best for smaller devices or wearables.
